IMPROVEMENT IN SMOKE AND STEAM BURNERS.

Specification forming part of Letters Patent No. 141,277, dated July 29,1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that we. JOHN W. KINGMAN and ADOLPHUS EURGENS, of Laramiecity, in the county of Albany and Territory of Wyoming, have invented anew and useful Improvement in Smoke and Steam Burner, of which thefollowing is a specification:

Figure 1 is a detail vertical longitudinal section of the fire-box of asteam-boilerin which our improvement has been applied. Fig. 2 is adetail vertical cross-section of the same taken-through the line .70 wof Fig. 1.

Our invention has for its object to prevent the waste of heat and fuelconsequent upon replenishing the fire with cold fuel; and to utilize thevolatile gases, smoke, &c., expelled when coal is added to the fire; andto enable the fire to be used with a less draft than is necessary whenthe fire-boxes are constructed in the ordinary manner; and to utilizethe hydrogen of water as a fuel, by combining superheated steam withvolatile carbon. The invention consists in an improved mode of utilizingsteam and smoke in furnaces, as hereinafter described.

A represents the fire-box, and B the grate, of an ordinary steam-boiler.O is a box or trough, open at its top, and which is supported uponpivots attached to its ends, and which work in bearings attached to thefront and rear walls of said fire-box A. The coal to replenish the fireis first placed in the box 0, where it is exposed to the full heat ofthe fire. This heat expels the more volatile gases, which, with thesmoke, are at once ignited and consumed. At the proper time the box 0 istilted, and the coke is dumped into the fire, so as to replenish withoutchecking it. D is a steam-pipe leading from the exhaust of the boiler,or from the boiler, and passing through the fire upon the grate B. Thepipe D is connected, by a hollow pivot or other convenient means, with apipe, E, which extends along the bottom of the box 0, and has numerousholes formed in it.

By this means the steam is superheated while passing through the pipe D,and is discharged among the coal in box 0, where it is decomposed,mingles with the smoke and volatile carbon from said coal, and isconsumed.

In thisw'ay the steam from the boileris economically burned as fuel.coal in this way before it is placed upon the fire, it will not benecessary to have so strong a draft, and the exhaust steam does not needto be discharged into the smoke-stack to increase the draft, but may beused to heat the water fed into the boiler, by leading it into aspray-chamber in the tank, and thus in some measure securing theadvantages of a con- (lensing-engine.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A pivoted fuel-holder, O, in combinationwith the grate B and furnace A, as and for the purpose described.

2. The steam exhaust pipe D, arranged in relation to the pivoteddrying-trough 0, to discharge thereinto, as and for the purpose setforth.

3. The combination of a pivoted box or trough, O, superheating-pipe D,and distributing-pipe E, with the fire-box of a steamboiler or asmelting-furnace, substantially as described. JOHN W. KINGMAN.
